Some Allentown middle school students got a break from classes Monday.

Trexler Middle School, at 851 N. 15th St., was evacuated because of an odor of natural gas inside the school.

Students, staff and faculty were relocated to other locations, said Kimberly Golden-Benner, a spokeswoman for the district, adding that the students were to be dismissed from those locations at their regular end-of-school-day time.y.
